GTechniq W4 Citrus Foam

Ultra-concentrated and LSP safe!

GTechniq W4 Citrus Foam is a unique take on the traditional foaming shampoos. Rather than being loaded with caustic chemicals that will strip a coating, sealant, or wax from the surface, it simply removes the dirt, grime, and dust buildup and leaves the good stuff alone. GTechniq W4 Citrus Foam combines an effective citrus degreaser with a strong foaming agent – making it tough on dirt, grime, bug remains, and bird droppings, but gentle on your protecting agents.

Treating your vehicle to a foam wash is not only fun for the user, but also very effective on the dirt and grime that’s built up on your surface. The foam clings to the surface, breaking down contaminants and making their safe removal very easy. GTechniq W4 Citrus Foam has taken that idea one step further by incorporating a pH neutral citrus cleaner into the formula – now you can foam wash your car without stripping your coating or wax!
GTechniq Citrus Foam, when used with a foam gun or foam cannon, produces an amazing amount of suds that will release the hold dirt and grime have on your vehicle.
GTechniq W4 Citrus Foam is an extremely concentrated formula:
Dilute 1:400 for use with a foam lance or,
Dilute 1:25 for use with a pump sprayer.

This allows the user to get the most out of their foaming shampoo, and puts the cleaning power in their hands. GTechniq W4 Citrus Foam is 100% biodegradable, non-caustic, and pH neutral – everything you would want your heavy cleaning foam car wash shampoo to be!

Directions for use:
  • It is recommended you use GTechniq W4 Citrus Foam with a foam gun for best results.
  • Use a dilution of 1:400 for lightly soiled surfaces, and a dilution of 1:200 for heavily soiled surfaces.
  • Coat your car in a layer of GTechniq W3 Citrus Foam suds and allow to dwell for approximately 5 minutes. This will loosen the grip that contaminants have on your paint and allow for their safe removal. Do not allow product to dry on surface.
  • Rinse thoroughly

Best Pre-Wash Out There
This is by far the best pre-wash on the market.

It easily removes dirt without any contact, making for less marring and safer contact washing.

It’s perfect for dirtier than normal cars.

Smells great too!
ProsPerfect pre-wash Eats dirt Safe on paint and coatings Makes contact washing safer Light citrus scent
Eats away and grime and bugs
When this soap is used as a pre-wash foam it is fantastic. I lay down a thick layer of foam on a dry car, let it dwell for a few minutes while I get my buckets set up and then go back with the pressure washer and the car basically looks clean. The only things I have ever seen stick to the paint are road grime stains when it rains and that grime dries to the car. But surface dust, grime, and bug crap all come right off after using W4. I absolutely love this stuff.

it's ok
Purchased this based on internet review. Looking for a good pre-wash. Tried both rcommended dilution ratio in a foam cannon and pump sprayer and the product does not work. Will play with dilution ratio to see if I get better results.
ProsSmells good
ConsDoesn't work
